NEW JERSEY, LSSIGNOR 150 THE BRUNSWICK-BALKE- COLLENDEE COMPANY 01 NEW YORK,

01 NEW YORK, N. Y1, .A CORPORATION OF Application filed December 9, 1811'. Serial No. 864,739.

To all :wkom. it may concern:

Be lt'known that I, Join: W. HYA'I'I, 8. c tizen of the United States, residing at Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Compressed Wooden Articles, fully described and represented in p the following specification and the accompanying drawings, forming a part -ofthe same.

This invention relates to certain improvements in compressed wooden articles.

In U. S. Patent No. 987,368, granted to yatt, March 21, 1911, there is dis, producing compressed closed a method of wooden articles, the method consisting generall in subjecting a block of wood to pressure oth transversel of the fibers and longitudinally of the fibers. The patent further discloses the production of completed wooden articles by finishing the wooden block to form the articles after the compression operation has been completed. The specific steps disclosed for ,carryin the method referred to into effect result 1n the production of a wooden block the fibers of which are compressed, as stated. throughout the entire block, the article thus produced being characterized by a special toughness, hardness and resiliency. In certain wooden articles it is unnecessary and undesirable that the-entire article be subiected to pressure. for the reason that it won (1 be increased considerably in weight thereby, and for the further reason that the use to which the article is put does not require that it be compressed throughout. 4

The present invention has for its object to produce an improved compressed woodenartlcle, the compression being confined tov a limited section or sections of the articles.

A further object of the invention is to pro- I 'duce an improved wooden game implement .of the invention will be hereinafter more fully described and its lstics pointed out. w I,

In the drawings: Flgure 1 represents'in' particular characterside elevation, and partly in section, a. game pin embodying the invention. Fig. 2 is a longitudinal section of'the lower part of the pm shown in Fig. 1, on an enlarged scale.

Fig. 3 is a diagrammatic side elevation, partly in section, illustrating generally an apparatus which may be employed for produciug the game implement referred to.

Articles constructed in accordance with the invention in its best form, will exhibit a limited section or portion which has been condensed by heavy pressure; exerted both transversely and longitudinally of the grain. The article selected to illustrate a concrete embodiment of the invention is a game pin.

,The game pin, marked 1 in the drawings,

has a compressed zone, indicated at 2. lo-

cated at the base of the pin. The fibers of the wood in the remainder of the pin including the fibers within the zone, this part being marked 3, remain in their natural or oncompressed condition. The pin, therefore, exhibits a zone at the base thereofwhich is exceedingly hard and tough. As the wear on a game pin has been found to be-l'argcly at its base and as any chi ping or uneven wear at the base may ren er it impossible to properly position the pin and -therefore destroy its usefulness, the compressed zone is of great value in increasin pin and this increase is e ected without un uly increasing the weight of the pin.

Patented July 29, 1913.

the life of the,

This compressed zone in woodenarticles has the further advantage that the wood within the zone remains in its natural condition, so that it maybe readily worked when desired. Where the -invention is embodied in a game pin, this enables the usual cavity at the base of the pin, indicated at 4, to be readily formed therein.

A suitable apparatus for forming a game pin in accordance .with the invention is illustrated in Fig. 3. In this figure there is illustrated a mold'5 having a tapering recess, as 6. The blank from which the pin .is formed is indicatedat 7, and 8 diagrammatically illustrates a pressing agent or plunger which will be actuated mechanism adapted to produce a heavy pressure. The outline of the lower end of the blank before compression is indicated by dotted lines. in Fig. 3. As the pressure.

is exerted the blank is driven into the tapering mold and into the position shown in full lines in Fig. 3, with'the result that a compressed zone ]will be formed at the lower end only of the blank. This zone is coincident circumferentially with the exterior surface of the blank and will extend inward varying distances according to the amountcording to the character of the article it is of taper given the mold, but there will be an uncompressed portion in the interior of the blank and this uncompressed. portion will be driven down into the opening 6 so as .to form a pro'ection 9 on the lowerend of the blank. hen the compression 1s completed, the blank is removedand turned, or otherwise fashioned into the completed pin.

While the formation of a compressed zone presents certain advantages, it is to beunderstood that the invention may be em-' bodied in articles in which the entire crosssectional area of the, article'is compressed throughout a limited portion of the article. Where, however, articles have an entire cross-sectional compressed portion, the compression will be produced by subjecting the articles to heavy condensing pressure both transversely and longitudinally of the grain, according to the method 'setforth in the Hyatt patent before referred to, the apparatus employed being varied, of course, ac-

desired to produce.

While the game pm illustrated is com-. J

pressed at one end only, itis to be understood that the invention is not limited to game pins or to game pins which are com-,

alley either end up. In making candle pins both ends should be compressed. v

The invention may also be embodied in other articles, such, for instance, as billiard cues. It is customary to make billiard cues of two parts, the handle portion of the one being made of much heavier wood than the remainder of the cue, the handle being'joined to the main portion in any suitable manner. It is further customary to provide the tip of the one with an ivory collar. A one compressed in accordance with the invention may have its handle portion heavily compressed to give the necessary weight, and the tip may also be compressed to gain the advantage now attained by the use of the ivory collar, the remainder of the one being .left in its uncompressed condition.- It will .the invention.

In constructing wooden articles embodying the invention the best practice is to 'make a blank or block which is generally shaped to that which the article is to finally have and then to compress the blank, the

final shaping being done after the compress1on.

The invention maybe embodied in articles other than those which have been heretofore specifically referred to.

What is claimed is:

1. A wooden article having the fibers of the wood throughout aportion only of the article compressed both transversely and longitudinally, the fibers of the remainder of the article being in their natural uncompressed condition. a

2. A wooden game implement the fibers of the wood being compressed bot-h transversely and longitudinally at an end, the fibersin the remainder of the implement remaining in their natural uncompressed condition.

3. A wooden game implement having its fibers compressed to form a tough, hard zone, the fibers within the zone being in their natural uncompressed condition.

4. A Wooden game pin the fibers of which are compressed to form a tough hard zone at an end of the pin, the fibers of the remainder of the pin and within the zone being in their natural uncompressed condition.

In testimony whereof, I have hereunto set my hand, in the presence of two subscribing witnesses.
